When we are being taught how to do something, we must listen to the person training us. If we don’t listen to the trainer, we won’t know or understand what we need to do. The same applies to our Christian faith, in order to learn from God, we must listen to Him. Added to that we must take time to also talk to Him, to tell Him our deepest fear, our greatest joys, those things that are sitting heavy on our heart, and to seek His forgiveness for those times when we have done wrong.
The key to being a Christian is to listen to God and speak to God in your prayers.
